Airplanes Don’t Fly Because the Air “Goes Faster” Over the Top of the Wing

The title is the common explanation of flight: the air is split at the front of the wing, and most go faster over the curved top, and be less dense on the top, to meet the air going underneath the wing.

This is wrong. I knew that, but I still repeat this story because I’m just not fully cognizant of the real story of lift.

Here is a very good explanation of how lift works, and the light bulb moment for me was Figure 10, showing how a single wing acts like a downwardly angled air scoop.

Perhaps we should be teaching boys who want to wear homemade wings to strap a piece of sheet metal ductwork, open in front and back, to their arms before they start their take-off run!
